APPARATUS FOR TRANSMITTING PBWER.

Specification of Letters Patent. Patented Apr. '18, 1911- Application filed March 26, 1910. Serial No. 551,654.

To all whom, it may concern Be it known that I, FRANK ll. SUMMER..-

following to he a full. clear. and exact. de-

seription of the invention, such as will enahle othersskilled in the art to which it appertains to make and use the same. reference being had to the accompanying drawings,

and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in apparatus for transmitting power and involves the employment of a mot r having two members arranged to rotate in reverse direction. the two members being directly connected with two gears mounted on a shaft to be rotated or with'thfe truck of'a velllClC, as acar. in such 'a manner that the oppositely rotating i'nemlwrs eoimerate to transmit motion to the shaft or the two sets of traction wheels in the same direction.

Provision is made for stopping one member of the motor \vhereh \"the othermeniher will rotate at approximately douhle the: speed. lleuce. my improved constructionl may he utilized for changing the gear lrom a high to a low or vice versa.

\Vhile I prefer to employ an elect rie inotor, it is evident that any motor having two memhers, mounted to rotate in reverse directions, may he employed. v .llaving hriettv out lined my improved eon- 5 struction. I will proceed to (ltHlllJt the r-tllllt f in detail. reference being made. to the 'aeeom- 253 of the motor is provided at one extremity partying d 'awing in which is illustrated an embodimen thereof.

traction wheels of the axles are propelled in a given direction.

The same reference characters indicate the same parts in all the views. I

Referring-first to Figs. 1 and 2, let the numeral desiguate a shaft; to be rotated and upon which. are mounted an exteriorly eogged wheel 6 and an interiorly cogged' wheel .7. The wheel 6 is normally fast on -the shaft. heing spline'd thereon as shown at the'left of Fig. 1. The gear 7 is normally loose on the shaft hut may be connected to rotate therewith through the medium of two clutch memhers Sand 9. the member 8 heing formed integral with the wheel 7 while the memher 9 is splined on the shaft and movable longitudinally into and outof on gagement with the clutch memher 8. \Vhen it is desired to cause the wheel 7 to rotate with the shaft. the two clutch members are thrown into engagement through the me- (llUl-ll of a lever 10 fulcrumed at l. and having a forked head 13 provided with pins 14 which enter a groove 15 formed 'in the clutch member 9 on opposite sides. By virtue of this connection the clutch member 9 is free to rotate with the shaftavhile the lever 10 remains staiionanv. The lever 10 is'also connected hv means of a rod 16 with one arm 17 of a lever 1 fnlcrunied at '19 and connected as shown at 2tl-with a hamlhrake 21 engaging a zone 22 of the field member 23 of a motor 24. 'hen it is desired to lo'clcthe liehl' meinher against rotation. the lever 10 is. shifted to the position shown in Fig. 1.

whereby the :clul'cll incinher 9 is interlocked In this drawing: Figure l is a top plan Z view showing a longitudinal section taken through a motor having its two oppositely rotating memhers connected to rotate a shaft in a given direction. the two motor menihers being-respectively eonneeted in operative relation with two gears mounted on the shaft to be rotated. Fig.2 is-a side elevation of the same. Fig. 3 is a side view showing a modified form of crmstruetion. in which the two opp itely rotating motor members are connected with gear; fast on the two-axles of a cantruck in such a manner that the two with the clutch memher S siuuiltaneouslv with the locking of the tieldiueinher of the motor against rotation. This field member Adjaeentthe journal box the armature shaft is equipped with a pinion 37 meshingwith the exterior gears 38 of the gear wheel tact 44, and thence source of electricity 1a pole changer 40 lmembers are rotatingin reverse thetwo oppositely 6 which is splined on the shaft, as heretofore stated, and as shown at From the construction just described it will be understood that when the two motor directions, I rotating .members, by virtue oftheir connection with the interiorly and exteriorly cogged gears on the same shaft, will operate direction. However, if it is desired to 1ncrease the speed of the apparatus'is carrying a light load, the field member of the motor may crating the band-brake, thus allowing the armature member to rotate at an increased speed.

The current enters the motor from a (not shown), through having two sets of conbeing designated 41, 42, 43 and 46, 47,48 and 49;

from one pole of facts, one set 44, and the other set- 45,

a conductor 51 to a brush 52 which engages a contact ring 53 carried the field member oftlie motor which is also equipped with other similar contact rings designated ,54, 55' and 56, respectively.

.after finally passin 80 to the contact ring From the contact ring 53, the current passes through a conductor 5.7 to one set of coils 78 of the field member of the motor, and through all of the said 79 through a conductor 54, whence it passes brush 58, and a conductor 59 to changer an to a brush 61 and thence to a contact ring 55, whence it passes through a conductor 62 to a section 63 of the commutator, finally passing from coils, it leaves a coi through a I thec'ommutatonsection 64 through a conductor 65'to thecontact ring 56, whence it asses through a brush 67 and a conductor 68 to the contact 41 of the pole changer, and thence through a conductor 69 to the conthrough aconductor 7O to the other pole of the electrical source.

When. it is desired to reverse the motor or cause its rotatin members to respectively rotate in reverse directions, the polech'anger will be given a partial rotation through the instrumentality of the crank 71, in which in-Figs. 1 and 2 is in use,

event the current will enter and leave the motor as before, except that the travel of the current through thg conductors 60 and 68 will be in reverse directions, as indicated by the dotted arrows adjacent the said con- .ductors (see Fig. 2)

I When the form of construction illustrated assuming that the field member, as well as the armature member of the motor,

' motor members will revolve in reverse directions and 'their reversely. rotating pinions 37 'and 29 will rotate the gears 6 and 7 mountthe said shaft ina given shaft, as when. thebe locked by opthe is free to rotate, the two 'by'virtue .of the. fact that one pinion engages'an extcriorly cogged'gear while the other pinion engages an interiorly cogged gear. It will be understood that when both motor members are rotating, that the shaft to be rotated is given a relatively low speed and the low gear of the apparatus may be said to becmployed. Now if it is desired to increasethe speedof the shaft, the bandbrake 21 is applied'to the field member of themctor whereby the movement of the latter is stopped. Simultaneously with the setting of the brake, the clutch member 9 will be disconnected from the' clutch member 8 of the wheel 7 ,thus allowing the shaft ed 'on the same shaft in the same direction,

42 by I-bcams 73 carrying bearings 74 and 75 in which the armature shaft iourn aled. Thestub-shaft rotates with-the field member 23 of the motor the same as in the other form of construction. However, upon the stub-shaft 25 is' splin'ed member 7 6 engaging a clutch member 77 fast on a short shaft 81 'ournaled in a bearing 82 carried by a third I-beain 83;

The motor construction and the manner of supplying the same stantially the same as shown in Figs. 1 and 2, and it will therefore not be necessary to describe these tion with Fig. 3. 1

Upon the armature shaft 32 is mounted and made fast a pinion 84 meshing witha assumed is the axle of a car carrying traction wheels. The short shaft 81 is also equipped with a pinion 87 meshing with a gear 88 fast on an axle 89 which it may also be assumed is av car axle carrying traction wheels in the-same manner as the axle 86. Furthermore, it may be assumed that the reversely rotating motor members are utilized to operate the truck of a car, the connec- .tions being such that the reversely revolving members cooperate to drive the truck in the same direction. Now if it. is desired to lock the field member of the motor against rotation, a lever 90 fulcrumed at 91 and having a forked end 96 provided with pins 93 engaging a groove 94 in the clutch mem ber 7 6, is operated, to disconnect the clutch member 7 6 from the corresponding member applied to the field member ofthe motor, which is locked against rotation, through. l the instrumentality of a rod 92 connecting a I clutch with current, is subfeatures in detail in c0nnec-- 5 to rotate in the gear. 7 without turning This is necessary since the field is locked against mov'e- Y lnthe form of construct-ion shown in I 3, the motor is suspended from the frame a 32 and the stub-shaft 25 are respectively gear 85 fast on an axle 86 which it may be.

rotation. necessary since it would not be to lock the axle 89 and its traction wheels against rotation; but by breaking the connection between. the two shafts 2'5 and 81 when the field member is locked against movement, all' difiiculty is overcome. When it is again deslred to allow the field member of the motor to rotate, the clutch members tion of the lever 90, and' the band-brake 21 is simultaneousl released.

Having thus eseribed my invention, what I claim is:

The combination with a car truck to be operated, of means for operating the same, comprising gear wheels respectively mounted on the truck axles, a motor having two members mounted to rotate in reverse directions, a direct connection between the respective members of the motor and the gears of the car truck, whereby when both motor members rotate'theycooperate to impart motion to the truck inagiven direction, means for locking one of the motor members againstrotation, and an operative connection between the said means and one of the gear wheels mounted upon the axle, where y as one motor member is locked against motion its connection with the truck is broken, substantially as described.

2. The combination with a vehicle truck to be operated, having a pair of axles, of gears fast on the respective axles of the truck, and a motor having two members mounted to rotate in reverse directions, and a gearing connection between the respective motor members and the gears of the truck, whereby the two mot'or members will cooperate to impart motion to the truck in a given direction; means for locking one of the 'motor members against rotation, and

' means for simultaneously breaking the con-- nection of the 'said member with the truck,

This construction is evidently racticable with the locking of the said member against rotation, substantially sis-described.

3. The combination with a vehicle truck having two members arranged to rotate in reverse directions, of a earing connection between both motor menibers and the truck whereby the reversely rotating motor members cooperate to drive the truck in' a 'ven direction, a brake for locking one o the motor members against rotation, means for operating the brake, and an operative connection between vthe brake-operating means and the motor member acted on by the brake, whereby as the one motor member is locked against rotation, its connection with the truck is broken, substantially as described.

A. The combination with a vehicle truck to be operated, having a pair of axles, the two axles of the truck being respectively equipped with two gear wheels, of a motor having two members arranged to rotate in reverse directions, a connection between the respective motor members and the respective gears of the vehicle truck to be operated, and means breaking its connection with the truck, substantially as described.

' 5. The combination with a vehicle to be operated, having a pail-of axles, the said axles being equipped with two gear wheels, of a motor having two members arranged to rotate in reverse directions, and a direct connection between the respective motor members and the respective gears of the vehicle axles, a brake for locking one of the motor members against rotation, means for operating'the brake, and an operative connection between the brake operating means for simultaneously locking one member of the motor against rotatiomand and one of the gear wheels of the axle,

whereby as one motor member is locked against rotation its connection with the truck of the vehicle is simultaneously broken, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
